text: The helicoradian (Loreyu in Navi) is a carnivorous plant that has red spiral-leaves. The plants are up to  tall and, when touched, instantly curl and collapse into themselves. They are zooplantae, part animal, part plant. They are first seen when Jake wanders off into a forest of helicoradia and touches multiple leaves, at which they retract and coil up to reveal a hammerhead titanothere behind. According to Avatar designer Craig Shoji, the behavior and design of the helicoradian' was based on the Christmas tree worms, tube worms that reside on coral reefs. In the video games, the species has the ability to heal the player.
